I published this recently:

http://vixyandtony.bandcamp.com/track/no-hurry-2012

To publish the song, I had to send Bandcamp the full-resolution WAV file of the final bounce of the mix. Bandcamp creates the MP3/FLAC/etc encoded files themselves.

The resulting MP3-320 that I downloaded from Bandcamp does not appear to have any embedded lyrics inside the file when I view it in a binary editor. However, when I play the file in Windows Media Player, I see lyrics. And they're correct, too, including the recent correction we made to the lyrics.

Does anyone know the source that Windows Media Player is using to gank the lyrics?
